Earlier this year, Apple confirmed that it’d be supporting end-to-end encryption with RCS in a future software update. At the time, iOS 18 was still the latest version of iOS – thus implying that the upgrade would come as part of the next round of software – iOS 26.
So far, end-to-end encryption is yet to ship. That’s not the only thing though. The upgrade to end-to-end encryption would’ve also necessitated other major upgrades to the RCS protocol, and as of iOS 26.1 beta, it’s all still missing.
